The heavy rainfall poses a significant flood risk, particularly in low-lying areas and locations prone to poor drainage. Basement apartment residents are especially vulnerable and are advised to prepare for potential flooding. The National Weather Service has highlighted the possibility of life-threatening conditions in areas experiencing the heaviest downpours. Strong thunderstorms could also bring isolated damaging winds, primarily affecting Northeast New Jersey and the New York City Metro area. Commuters and residents are urged to exercise caution, as flooded streets and subway stations could create hazardous conditions.
